EpiServer : How to Check Whether Page Exists?

Question

Is there a way to gracefully check whether a page exists in EpiServer CMS 5 (given a pageId integer) without having to catch the PageNotFoundException thrown by

DataFactory.Instance.GetPage(pageReference)

(EpiServer will happily create a PageReference using a non existing pageId).

Surely I can check whether a page exists without throwing an exception or doing a massive loop?

[EPiServer CMS 5 R2 SP2] No, not without bypassing the page cache and that is more expensive than catching the exception.

I find it nice to do the catching in an extension method:

public static bool TryGetPage(this PageReference pageReference, out PageData pd)
{
    try
    {
        pd = DataFactory.Instance.GetPage(pageReference);
        return true;
    }
    catch (Exception)
    {
        pd = null;
        return false;
    }
}

Why not return the `PageData` object instead of a bool and let the exceptions return as a null? – Eric Herlitz Oct 06 '14 at 18:21
I like the look of the code: PageData pd; if (pageRef.TryGetPage(out pd)) { // use pd } Nicer than having to null check. – Johan Kronberg Oct 27 '14 at 20:44

There is a static method of PageReference which should help:

PageReference.IsNullOrEmpty(pageLink)

PageReference.IsNullOrEmpty() only checks if the passed page reference is constructed correctly or not null, not if the acutal page exists or not. – Johan Petersson Feb 12 '13 at 13:34
